In order to guarantee that a software system solves a certain problem, it is necessary to understand and define the problems to be solved. However, the identification and definition of problems is not an easy task. Therefore, when developing a new software system, it is necessary to focus on three dimensions, as described by van Lamsweerde (2009). These three dimensions are shown in the following Figure 1. why? what? who? software-to-be objectives functional services, constraints people devices existing software Figure 1: The why, the what, and who dimensions Briefly describe why a system is needed? What need to be addressed in the system and who in the system will fulfill those needs?
